That depends upon other facts we don’t have.
Such as where in the world you live, what currency you use, the service history of your car, the age and condition of the tyres and exhaust system, and local market price variations.
There will be online price guides for your country which give an approximate value, and most offer the choice of paying for a more accurate estimate by entering more details.
Or you can search ebay for your exact make and model with similar mileage and then use the search filter “completed listings” to see what they actually sold for as asking prices are almost totally irrelevant.
Ultimately, it’s only worth whatever someone will pay for a 22/23 year old Civic and what you’re prepared to accept. That may sound odd, but if there’s few potential buyers when you sell then as there are always lots of old cars for sale, it becomes a buyers’ market. If yours is in exceptionally good condition then if it attracts many potential buyers it will be a sellers’ market.
